Trying to run the digitizer for just one detector and not remembering the available options, I’ve tried :
digitizer-workflow --help
and got a crash. Is that expected ?

Looks like indeed the digitizer-workflow requires that simulation actually ran in the same area in order to work, most likely because options are constructed from the GRP information. @swenzel probably knows more.
Anyways here is the result:
ALICE O2 DPL workflow driver (short help)
Executor options:
-h [ --help ] [=arg(=short)] print help: short, full, executor, or
processor name
-q [ --quiet ] quiet operation
-s [ --stop ] stop before device start
--single-step start in single step mode
-b [ --batch ] batch processing mode
-p [ --start-port ] arg (=22000) start port to allocate
--port-range arg (=1000) ports in range
-c [ --completion-policy ] arg (=quit)
what to do when processing is finished:
quit, wait
-g [ --graphviz ] produce graph output
-t [ --timeout ] arg (=0) timeout after which to exit
-D [ --dds ] create DDS configuration
--dump-workflow dump workflow as JSON
--o2-control create O2 Control configuration
-P [ --plugin ] arg FairMQ plugin list
-S [ --plugin-search-path ] arg FairMQ plugins search path
--control-port arg Utility port to be used by O2 Control
--rate arg rate for a data source device (Hz)
--monitoring-backend arg monitoring connection string
--infologger-mode arg INFOLOGGER_MODE override
--infologger-severity arg minimun FairLogger severity which goes
to info logger
--child-driver arg external driver to start childs with
(e.g. valgrind)
Global workflow options:
--tpc-lanes arg (=4) Number of tpc processing lanes. A lane
is a pipeline of algorithms.
--tpc-sectors arg (=0-35) List of TPC sectors, comma separated
ranges, e.g. 0-3,7,9-15
--onlyDet arg (=none) Comma separated list of detectors to
accept. Takes precedence over the
skipDet option. (Default is none)
--skipDet arg (=none) Comma separate list of detectors to
skip/ignore. (Default is none)
--tpc-reco-type arg Run TPC reco workflow to specified
output type, currently supported:
'tracks'
--configKeyValues arg Semicolon separated key=value strings
(e.g.: 'TPC.gasDensity=1;...')
